User's Manual
INTRODUCTION TO DI
•DI has many names, including Direct Input, Direct Injection, Direct Induction, and most
commonly, Direct Interface
•More than a simple 1/4" to XLR adapter, a DI box also matches level and impedance to
minimize noise in professional live and studio sound systems
•It converts an unbalanced signal into a balanced signal
•It converts a High Impedance (Hi-Z) signal into a Low Impedance (Lo-Z) signal
•It reduces high level outputs from Digital Pianos and Active Acoustic Guitars
•It isolates the sound system from the equipment on stage
•It provides a parallel output, so performers can retain local control of their instruments

OPERATION
1. Ensure that the volume levels of your instrument and sound system are set to the minimum.
2. Plug a balanced XLR connector into your mixing console or stage snake, then plug the other
end into the XLR Output jack on the sound block.
Note: All inputs are wired in parallel, yet isolated to separate the Left and Right sides.
3. Plug a 1/4" TS, Dual RCA, or 3.5mm cable into the appropriate Input on the sound block,
then plug the other end into any unbalanced sound source (e.g., instrument, device, or
computer).
4. If you are limited on mixer channels use the Sum Mono button to combine audio from the
L/R inputs to a mono signal. Both XLR outputs will carry all audio.
5. Increase the volume level of your sound source (e.g., instrument) to the 50% ~ 75% range.
6. Increase the volume on your sound system to the desired level.
7. If there is a buzz in the system originating from your instrument, use the Ground Lift switch
to isolate your instrument from the sound system.
8. If there is distortion from the input of the sound system, use the Attenuator switch to
reduce the instrument's level by -20dB.
